1. We expect many parents to state initially (in the 48 hours post-partum) that they would elect to have genome screening for their newborn if it were available. In the follow-up survey, half of study participants will receive hypothetical scenarios in which they will need to struggle with the probabilistic and ambiguous nature of the information that could be derived from genome sequencing. We will examine whether this alters their preferences. We will also explore whether parents who receive hypothetical genome screening results scenarios are more likely to alter their preferences than parents who do not receive hypothetical scenarios.
